Perkembangan tanah dari Tailing di ModADA PTFI : aspek reklamasi dan suksesi alami

Abstract

Tailings are residue of mining material after separation of valuable substances such as copper, gold and silver elements. Separation of these elements involves crushing of parent material to become fine particles and separation of the precious elements by flotation technique. Total amount of tailings produc ed by PT Freeport Indonesia are about 230.000 tons/day. These tailings are transported and deposited in the lowlands of Timika, Papua and confined in the two levees i.e East Levee and West Levee called as ModADA (Modified Ajkwa Deposition Area). The research had been done in ModADA, the property of PTFI in Timika, Papua from March to November 2005.
